Why can't I research any more caps or cores?
I have researched all the Wand Foci that directly connects to the Wand Foci research, Gold and Copper Caps and Greatwood Wand Cores but I can't research the next cap or wand core that's directly connected.
I've also researched these 2 Node Stabilizers and some Node Relay which were in the upper left corner however I am unsure if they were added by an add-on since they were hidden away.
I want to know how I can research the next cap and core as currently they remained grayed out?
